   • “Smart” supplement light (intelligent control of the light).

4. Image Quality Enhancements

   • 130 dB True WDR (Wide Dynamic Range) — helps handle very bright and very dark areas in the same scene.

   • Noise reduction: 3D DNR (3D Digital Noise Reduction).

   • Other image adjustments: BLC (back-light compensation), HLC (high-light compensation).

5. Smart / Analytics Features

   • Deep-learning based human and vehicle classification — helps reduce false alarms.

   • Perimeter protection: supports events like intrusion, line-crossing, region entry/exit.

   • Smart events: unattended baggage detection, object removal, scene change, audio exception.
